New Old Stock is a website dedicated to archiving license free, creative commons, and public domain images, curated by designer Cole Townsend. There are loads of pictures to choose from with subjects ranging from Ronald Reagan to rocket launches to skeletons playing piano to the peaks of Matterhorn.
Each photo includes a link to the original source, usually on Flickr, and those links are often handy with more information about the photo. All the photos are free, but for an additional fee (between $5 and $12), you can download “photo packs” which contain multiple web-optimized images which are all at least 1000 pixels wide.
As for the pictures on the free version of the page, they’re listed in no particular order, but on one handy page that seems to load forever with more and more images.
